Terrorist surveillance laws are set to expire this weekend after House Democrats defied the president and refused to approve a bill that would modernize intelligence capabilities. Angered Republicans claim this will undermine national security and endanger American lives. Democrats argue every order entered under the law can remain in effect for 12 months from the date it was issued and that the country remains safe and strong.

Just how dangerous is the situation? We'll ask the Director of National Intelligence, Mike McConnell live on "FOX News Sunday."

Plus, with another Obama sweep in the Potomac Primaries, Senator Clinton has some "must win" states in order to close the delegate gap in the race for the Democratic nomination. Can Clinton stop Obama's momentum in key upcoming states? We'll ask the governors in two of those battlegrounds — Obama-backer Governor Jim Doyle of Wisconsin and Clinton-supporter Governor Ted Strickland of Ohio.

Then, we'll look at how John McCain matches up against both Democrats. Joining us will be Fred Barnes of the Weekly Standard; Mara Liasson of National Public Radio; Bill Kristol of the Weekly Standard, and Juan Williams of National Public Radio.
